摘要:
Alkyl 3-oxobutanoates (alkyl: methyl, ethyl, allyl, isobutyl, t-butyl) were reduced enantio selectively to the corresponding (S)-alcohols by the fungus Rhizopus arrhizus and other Rhizopus sp. The best result obtained was with t-butyl 3-oxobutanoate, which was reduced by R. arrhizus with 99% enantiomeric excess and similar to68% isolated yield. (C) 2004 Published by Elsevier Ltd.
